(Reuters) -Australia winger Joseph Suaalii will miss New South Wales Waratahs' Super Rugby Pacific clash against the Canterbury Crusaders next week due to concussion after he was stretchered off in his side's 28-21 loss to the Queensland Reds on Friday.

Suaalii sustained a blow to the head just before halftime when he collided with teammate Andrew Kellaway at Sydney Football Stadium, but Waratahs coach Dan McKellar said the 21-year-old had not required hospitalisation after the incident.
